First, I would find the radius for both discs. To do so, divide the circumference by 2.
So.. 27.3/2=13.65. 22.5/2=11.25.
Afterwards, take the radius and use the formula: 2(3.14)r.
2*3.14*13.65＝85.722 and 2*3.14*11.25＝70.65.
Then, you subtract 85.722 from 70.65 which equals 15.072 which rounds to 15.

Answer:
75 kB
Step-by-step explanation:
let's say v the speed of transmission
v=20kB/4s=5 kB/s
Data downloaded =v*t=5kB/s*15s= 75 kB*s/s= 75 kB.
